7.2.1 Air fi ltering
NOTICE
Insuffi cient maintenance on the air fi lter
The power of the machine lessens and damage may
occur to the machine.
The fi lter cartridges (Fig. 5/e) for intake air, (Fig. 5/f)
for blowing air and (Fig. 5/h) for air charging must be
cleaned every month or more often depending on
how dirty they are by blowing out from inside to out-
side. In spite of cleaning the fi lters their separation
effi ciency will continue to deteriorate. Therefore the
fi lters should be replaced every six months.
Changing fi lters:
V-KTN (01
➝ 06) and (08 ➝ 10): Unscrew the outlet
grid (Fig. 5/G).
Undo the screw cap (Fig. 5/s) and the knurled knob
(Fig. 5/m). Undo the knurled nut (Fig. 5/o) and re-
move the fi lter cover (Fig. 5/k). Remove and clean or
replace fi lter cartridges (e), (f) and (h). Reassemble in
reverse order.
WARNING
Danger of injury when dealing with com-
pressed air.
When blowing through with compressed air, solid
particles may be carried along or powder dust swir-
ling around may cause injury to the eyes. Therefore,
when cleaning with compressed air always wear
goggles and a dust mask.
